WARNINGS:
-MCDI recommends choosing a high quality lead-acid battery or gel type. Most stores selling security equipment hold a variety of
power levels to choose from.
-If not charged, the battery will discharge. Ed does not provide battery supervision or charge to battery. Ed supplied with a
Molex NO lock type connector for battery. This connector has a red and black wire for connection to battery. Red is positive,
black is negative. Do not invert polarity: severe damages may result.
-Do not use a battery supplying more than 14V DC. Significant heat dissipation will result and may damage unit. Do not use a
battery showing signs of tear, leak or corrosion.
-Never connect a faulty or drained battery to the Ed.
-Ed cannot charge a battery.
-Ed cannot be powered by USB port.
Battery time
To calculate battery time: Battery capacity (milliamp hours) / total current (milliamp) = battery life (hours)
Example with a fully charged new battery– typical 200mA drain from:
12V 600mAh
3 hours
12V 1Ah
5 hours
12V 70 Ah
350 hours
Always refer to battery manufacturer application notes on charging, using and discharging a battery.
Using 2 x 6Vbatteries (serial connection)
In using a serial connection, voltage of each power source will be added and delivered to Ed.
Using 2 x 12V batteries (parallel connection)
Using a parallel connection of batteries, resulting current to Ed is the sum of current provided by each source. Batteries should
be matched to prevent heating among power components.
Battery charger
A battery along with a battery charger may be used. Using a supervision circuit is preferable. MCDI tested and recommends
Altronix PM212 and a 12V battery. A circuit like the Altronix PM212 will insure a constant tension (9-12V preferred), battery
charge and battery supervision
Insure that your circuit delivers less than 14V to
Ed. Significant heat dissipation will result if using a power source of more than
13.8V. This may damage the unit of reduce life expectancy of
Ed.
-Verify installation regularly.
-Consult a qualified Electrician prior to connecting
Ed.If you are using a battery, a battery charger and/or equipment
USB Power This power option is not suitable for Ed. Ed will not be powered over USB.
Ground post Refer to a qualified electrician to insure electrical installation is made according to local law and regulations.
As a safety for users and the Ed
alarm receiver, Ed should be grounded through the PC chassis. A wire of AWG #14 should be
used along with a lug if the PC is not fully grounded through the electrical connector. Ground connection must be maintained
and verified regularly to insure ground to earth is always present. Unit will not function correctly if not properly grounded.
